An auristatin compound conjugate is provided herein. The conjugate comprises a protein based recognition-molecule (PBRM) and a polymeric carrier substituted with one or more -L
D
-D, the protein based recognition-molecule being connected to the polymeric carrier by L
p
. Each occurrence of D is independently an auristatin compound having a molecular weight ≦5 kDa. L
D
and L
p
are distinct linkers connecting the auristatin compound and PBRM to the polymeric earner respectively. Also disclosed are polymeric scaffolds useful for conjugating with a PBRM to form a polymer-auristatin compound-PBRM conjugate described herein, compositions comprising the conjugates, methods of their preparation, and methods of treating various disorders with the conjugates or their compositions.
本文提供了一种auristatin化合物结合物。该结合物包括以蛋白质为基础的识别分子(PBRM)和多聚载体,该多聚载体被取代了一个或多个-LD-D,蛋白质基础的识别分子通过Lp连接到多聚载体上。每个D的出现都是独立的,具有分子量≦5 kDa的auristatin化合物。 LD和Lp是连接auristatin化合物和PBRM到多聚载体的不同连接物。还公开了用于与PBRM共轭形成在此处描述的聚合物-auristatin化合物-PBRM结合物的聚合物支架,包括结合物的组成,其制备方法以及使用结合物或其组成治疗各种疾病的方法。
